BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into “Drive” or “Reverse”.
WARNING
When you intend to park or stop the
vehicle with the engine on, be care-ful not to depress the accelerator
pedal for a long period of time. It
may overheat the engine or exhaust
system and cause fire.
WARNING - Driving under
the influence of alcohol or drugs
Driving under the influence of
drugs or alcohol is dangerous and
is one of the major contributing fac-
tors to the road deaths each year.Even a small amount of alcohol will
affect your reflexes, perceptions
and judgement. Driving while under
the influence of drugs is as danger-
ous or more dangerous than driv-ing drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-er who has been drinking or taking
drugs. Choose a designated driveror call a cab.

Automatic transaxle operation
The highly efficient automatic transaxle
has 4 (or 5) forward gears and one
reverse gear. The individual gears are
selected automatically, depending on the
position of the shift lever.
All normal forward driving is done with
the shift lever in the D (Drive) position.
To move the shift lever from the P (Park)
position, the brake pedal must be
depressed with the ignition switch ON.
✽✽
NOTICE
The first few shifts on a new vehicle, or if the battery has been disconnected,
may be somewhat abrupt. This is a nor-mal condition, and the shifting sequence
will adjust after shifts are cycled a few
times by the TCM (Transaxle Control
Module) or PCM (Powertrain ControlModule).
For smooth operation, depress the brake pedal when shifting from N (Neutral) to a forward or reverse gear.
E060101ANF
Transaxle ranges
The indicator lights in the instrument
cluster displays the shift lever position
when the ignition switch is in the ONposition.
P (Park)
Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the frontwheels from rotating.
WARNING - Automatic
transaxle
Always check the surrounding areas near your vehicle for peo-
ple, especially children, beforeputting a car into D (Drive) or R
(Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movementcan occur if these precautions
are not followed in the order iden-tified.
CAUTION
To avoid damage to your
transaxle, do not accelerate theengine in R (Reverse) or any for- ward gear position with the
brakes on.
When stopped on an upgrade, do not hold the vehicle stationarywith engine power. Use the serv-ice brake or the parking brake.
Do not shift from N (Neutral) or P (Park) into D (Drive), or R(Reverse) when the engine is above idle speed.

Releasing the parking brake
To release the parking brake, first apply
the foot brake and pull up the parking
brake lever slightly. Secondly depress the
release button (1) and lower the parking
brake lever (2) while holding the button.Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ONposition.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released while
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
WARNING
To prevent unintentional move- ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parkingbrake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.

Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilise the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going. ESP applies
the brakes at individual wheels and
intervenes in the engine management
system to stabilise the vehicle. The Electronic Stability Program (ESP)system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽✽
NOTICE
A click sound may be heard in the engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abruptmanoeuvres and aquaplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

Driving your vehicle
E070600AFD-EA Good braking practices
After being parked, check to be surethe parking brake is not engaged and
that the parking brake indicator light is
out before driving away.
Driving through water may get the brakes wet. They can also get wet
when the car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car to pull
to one side. To dry the brakes, apply the brakes
lightly until the braking action returns to
normal, taking care to keep the car
under control at all times. If the braking
action does not return to normal, stop
as soon as it is safe to do so and call
an authorised HYUNDAI dealer for
assistance.
Don't coast down hills with the car out of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tyre goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
WARNING
Never press the ESP OFF button while ESP is operating. If the ESP is turned off while ESP is
operating, the vehicle may go out of
control.
To turn ESP off while driving, press
the ESP OFF button while driving
on a flat road surface.
WARNING
Whenever leaving vehicle or parking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car whichcan injure occupants or pedestri-ans.
